To all whom it may concern:

Be it known that I, JULIUs J. BRELL, a citizen of the United States,residing at the city, county, and State of New .York, and whosepost-oflice address is 530 Qne Hundred and F ifty-ninth street, in sa1dcity, have invented a new and useful Improvement in Button Placing andReleasing ifkttachments for Sewing-Machines, of whlch the following is aspecification. p

The object of this invention is to provlde a device of this class,wherein a button is received prior to being stitched to a fabric andthen the button is so placed with regard to the sewing mechanism of themachine that the needle of the machine may pass through the variousholes of the button While the same is being sewn to the fabric. Thisobject is accomplished by my invention, one embodiment of which ishereinafter set forth.

For a more particular description of my invention, reference is to behad to the accompanying drawings, forming a part here of, in which'Figure 1 is a plan view of a structure provided with my improvement;Fig. 2 is a plan "iew of a portion of the mechanism for causing correctregistration between the holes of the button and the needle of themachine; Figs. 3 and 4 are side and end views of a portion of themechanism shown in Fig. 2; Fig. 5 is a side elevation of the structureshown in Fig. 1; Fig. 6 is a front view of my improved device lookingtoward the rear. This view is taken at right angles to the views shownin Figs. 1 and 5. Fig. 6 shows a detail of construction. Fig. 7 is aside elevation of the button clamping and holding mechanism; Fig. 8 is afront elevation of the clamping mechanism; Fig. 9 is a sectional viewtaken on the line 9-9 of Fig. 8, looking in the direction of the arrows;Fig. 10 is a side elevation of the button clamping and releasingmechanism; and Fig. 11 shows a cam plate and stop. A

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

My improved placing device 10 may be applied to any suitable sewingmachine 11 and the manner of its application will depend upon thestructure of the sewing machine. In the embodiment shown, the machine 11is provided with a suitable bed plate 12, which carries the mechanism ofthe sewing machine and the placing machine. In any event, the needle 13of the sewing machine is provided with a suitable thread 14 for sewingthe button 1 in place and this needle is mounted so as to reciprocate inthe arm 15 in the usual way. It is not necessary to describe .thedetails incidental to the mounting and driving of the needle, as theyform no part of my invention.

A second arm 16 carries a slidably mounted and "ertically disposed bar17 to which the clamping mechanism is attached. This bar 17 is normallypressed downwardly by means of a suitable spring 18 or any othersuitable device. This bar 17 has a projecting pin 19 which is adapted toengage a corresponding projection 20, so that when the needle mechanismis raised, the bar 17 may also be raised against the spring 18 and soare the parts carried thereby.

The lower end of the bar 17 is bent forwardly at right angles to form afoot 21 to which is secured by means of a suitable screw 22 a plate 23,on which the jaws 2 and 3 of the clamp are pivotally mounted, the jaw 2being pivoted at 24 and the jaw 3 at 25. These two clamps are normallypressed together by means of a suitable spring 26, as indicated bydotted lines in Fig. 9. Below the jaws 2 and 3 and slidably mounted onsuitable cap screws 27 is the cam plate (3. This cam plate 6 issupported directly below the jaws'2 and 3 by means of these screws 27and at one edge this plate 6 is suitably recessed at 7 for a purposethat will appear below.

The screws 27 ride in divergent slots 28, which are nearest together atthe rear and separated widest at the front, as appears in Fig. 11.Fromthis it appears that as this plate slides a slight distance forwardor back, the jaws2 and 3 are either brought to- I gether or separated,they are brought together on the forward movement and separated at therearward movement, as is obvlous.

The stop 4 is carriedby the plate 23 by means of a suitable cap screw 29that rides in a corresponding slot 30 in the plate 23, so

that this stop 4 may be adjusted for various sizes of buttons.

The spring 26 which holds the jaws 2 and 3 in proper relation, ispreferably mounted at its rear on a suitable screw 31, although itmay bemounted in any other suitable way, if desired.

It will be noted that the jaws 2 and 3 and the stop. 4 are bentdownwardly and forwardly near their forward ends, so as to carry thebutton 1 well below the level of the plate 23. The extreme front ends ofthese parts 2, 3 and 4 are made horizontal, the jaws 2. and 3 beingprovided with horizontal grooves 32 to carry the button 1.

From the foregoing, it is apparent that the jaws 2 and 3 may beseparated by shoving back the plate 6 and brought together by the actionof the spring 26, when pressure is removed from the cam plate 6. When,however, itis desired to make the machine automatic in this respect,this can be accomplished by providing a bracket 33, which is secured tothe head 16, as shown in Figs. 8, 9 and 10. The preferable way is to fixthis bracket 33 by means of suitable screws 34, but any other means maybe adopted, as desired. At the outer and forward end of the bracket 33is a pivot 35 which carries. a suitable cam 36 which has a bevel camedge 8,

which is adapted to enter the recess 7 of the plate 6. A suitable leafspring 37 is secured to the bracket 33 and normally presses this pivotedcam 36 against a screw 38, set in the- The forcing of the plate 6 towardthe rear swings the jaws 2 and 3 apart and thereby.

separates the cam 8 from the recess 7, the screw 38 being properlyadjusted for this purpose. This separation of the jaws takes place inthe first quarter of their elevation and thereafter they are free toreturn to their normal condition undisturbed by the cam 36 which isswung outwardly against the pressure of the spring 37. When the;

jaws separate, the button is left sewn to the cloth, and then the jawsare restored to their normal position and a new button is shoved againstthe stop 4 between the jaws 2 and 3. The mechanism for properly placingthis button with regard to the needle 13 will now be described. Thisneedle 13, as above stated, sews three stitches in each hole, or twelvestitches in all, in the embodiment of the invention herein shown anddescribed.

I The button remains stationary, while the needle is shifted after eachreturn movement from the button hole last entered. The button is rotatedbetween the parts 2, 3 and 4 by means of a spring pressed finger 5 whichis pivoted at 39 in a reciprocating link 40. This finger 5 has at itsupper end a suitable notch which receives a coiled spring 41 secured toa projection 42 on the link 40. This spring 41 is so made and disposedthat it tends to throw upwardly the lower end 'of the finger 5. The bed12 of the machine has several parts fixed therem,

"in any'suitable manner, one of which is a plate 43 and an arm 44 fixedto the plate 43 by means of a suitable cap screw 45. At the forward endof this arm 44 are mounted two parts which are held by a suitable screw46. The upper one of these parts is a suitable spring 47 which rests onthe link 40 and prevents the same from rising, except against thetension of this spring 47. The other part is shown in detail in Fig. 6*and comprises a plate 48, which is pivoted on.

namely a spring 47 on top, the projection 49 below and the upright 50 onone side. This leaves one side which is not controlled by a guide.

The 'rear end of the link 40 is connected by a suitable bolt or screw 51to the angle metal pivot 52 which is pivoted at 53 to a collar 54, whichis mounted on a suitable screw 55, so as to turn thereon. A projectingear 56 carries a coiled-spring 57, the other end of which is attached toa post 58 which rises from a slide 59. The slide 59 is normallyretracted by a coiled spring 60, which issecured to the post 58 atitsforward end and to a post 61 at its rear end. This post 61 rises fromthe plate 43 and is fixed therein. The rear end of the slide 59 isprovided with a large head 62 and a transverse slot 63 in which runs apin 64 on a lever 65, which is fulcrumed at 66 to a screw projectingfrom the plate '43. The other end of this lever has a suitable slot 67,in which is secured a pivot 68 which is adjustably mounted thereon andprovided with a suitable cord or cable 69 that runs to a foot pedal, notshown. By pressing on this foot pedal, the lever 65 has its pin 64thrown to the front of the machine against the tension of the spring 60and thereby forces the bar 40 to the front. While the jaws 2 and 3 areraised, a button 1 is inserted between them as will appear below. As thespring 60 causes the slide 59 to return toward the rear, when thepressure on the treadle is released, the spring finger 5 is drawn to therear, and while so being drawn, it wipes the button, enters a holetherein, if not already in a hole, and rotates the button on its axisuntil the button is turned to such an extent that it cannot be easilyturned any more by the withdrawal of the finger 5 and then the fingerleaves the button hole and gets clear of thesewlng mechanism. The actionof this finger is such that the button is turned so as to cause aperfect registration and the needle goes through the button hole set forit. This foot pedal also raises the projection 20 of the sewing machineand through it the projection 19, the bar 17 and plate 23.

The front end of the bar 40 is raised along with the plate 23 and bar 17and the parts connected therewith by means of a wire secured to asuitable screw 71 mounted on the plate 23. The pivot 53 lets this bar 40be raised against the tension of the spring 4-7. The screw 71 may, ifdesired, pass through a suitable slot 72 in a pivoted arm 73 which ispivoted at 74 in the plate 23. This arm 73 may press against the screw29 and so prevent the same from moving too far forward in the slot 30and the adjustment, because of the slot 7 2, can be made very nice, sothat the stop 4 will always be placed in right relation for the buttonplaced between the aws 2 and 3, although any of several sized buttonsmay be used in the machine.

Assuming the jaws ready to receive the button 1, the operation is asfollows: The jaws 2 and 3 are spring-pressed and pivoted and when thebutton is placed in the recesses 32 between them, it is pressed inwardlyto the stop 4 and there remains. The button 1 is inserted while atreadle is pressed and the clamping jaws 2 and 3 are elevated. As thebutton is put in place, as above described, it

presses against the spring finger 5 and forces the same ,inwardly aslight distance. As the clamp is lowered, the spring finger is alsolowered to correspond for a certain distance, but not the entiremovement of the clamp, and when the finger and clamp begin to separate,the spring finger begins to assume a vertical position and in soassuming, turns the button on its axis until the same is in properposition for the sewing mechanism of the machine. This occurs when theclamp is about three-quarters lowered and thereafter the button is inproper position. The further lowering of the clamp separates the fingerfrom the button and the finger thereafter remains in its normal positionand will not be swung on its vertical pivot until the next cycle of themachine, when the next button is inserted. The finger is pressedforward, as above described, by the treadle and when the treadle isreleased, the finger is drawn inwardly toward the rear of the machineand while being so drawn, forces the button against the stop 4. Thebutton is then sewn to the fabric in the usual manner, twelve stitchesbeing employed, three through each of the four holes of the button, andthereafter the sewing machine automatically stops with the needleelevated. The treadle is again pressed and the clamp with the jaws 2 and3 and the stop 4 is raised, as above de scribed. As the clamp rises, onewall of the recess engages the cam S and the plate 6 is shiftedrearwardly and thereby spreads the jaws 2 and '3 against the action ofthe spring enough to release a button. This separation occurs during thefirst quarter of the elevation of the jaws, and then the spring of thejaws forces the cam edge 8 out of the recess 7 and thereby permits theplate 6 to come forward and close the jaws to normal, where they remainand thereafter, the cam 8 1s not operative during the remainingthreequarters elevation and the next lowering of the clamp. The jaws 2and 3 are then in their normal position, and ready to receive a button,when the above cycle is repeated.

The feed of the cloth in the sewing machine takes care of the spacing ofthe buttons on the fabric.
